vTo LL -WHoM IT MAY concluait:

.Be it known that-I, WIIIJLIAMC. JOSLIN, of Putnam, in theioounty of Windham, and State ofonnecticnt,

have invented afnew and usci-'ul Machine foi` Rolling the Top Drawing-Rolls, and Cots thereon, of Spinning- Frames', of which `the following is a full,'clear, and exact description, reference being had'A to the accompanying drawing,` forming part of this specification, 'and in wl1ich 'Figure lrepresonts a vertical transverse section of a machine, for the purpose above "described, constructed according to my invention,and

f Figure 2 a. plan of the saine, with the upper rolle-r removed. .Similar letters of reference indicate corresponding parts.

The object of this, my invention, isvthe construction ofa machine, which shall operate by rollerlpressure or action,to roll and give aruniforin surface to the top rolls of drawing-.rolls of spinning-frames, either when the same are merely clothed up or after the cots are drawn on; and my invention consists in a. certain combina' tion of' lower rollers, driven to travel ina like direction, and upper'loose or free roller, made to rise and fall ai intervals for reception and vdelivery of the work, which is fed invat one` side ot'v the machine, and `del'iuered at the opposite. A Y i A i l Referring to the accompanyingdrawing, A A are the Isidev uprights or frame of the machine, of any suitable construction, and carrying atlower pair of'horizontal rollers, B and @arranged in closel proximity, and parallel to each other. Over these rollers, at a suitable distance from them, is a Vthird horizontal roller, D, hung in vertically-slidingfamesE, and raised, atv intervals,` by the action of cams F on a'shaft, G, acting under or against bowls H, connected with the sliding frames, ,ortho same may be lifted and lowered by any suitable mechanical devices. This latter vrollerfmay be hung loose or free, to rotate with the work, while the lower rollers may be driven by belts and pulleys from theshaft G, to travel as indicated by their respective arrows.

l 'The rolls I, to' be worked,"(shown by red lines,) after they have'been suitably clothed up--that is, covered with cloth orvothe'r suitable material on their peripheri, or itimay be only after their outer covering of leather or co'ts is drawn on them, either'or both -are laid on an-inclined table, J', and each time the upper roller, D, is raised by the action of thecams F, a roll, I, is admitted between the rollers B C D, that, in-'th'eir rotation and action on said roll I, serve to roll tightly the clothing or cot, and to give a uniform surface to the same.

The roll thus worked is delivered into a trough, K, by the next succeeding roll-feed, in striking .orvdriving it out on the rising again bf the upper roller D; `In this way are great celerity and perfection attained in finishing work of the character described. i

What is here claimed., and desired to be secured by Letters Patentfis- The combination of the rollers B .0, feeding and delivering-boards J K, and roller D, the'latter having an intermittent motion toand from the others, all arranged for operation substantially as and for the-bpurpose specified.
